MiniTuner

If you can never put your hands on your guitar tuner or you simply don't have an ear for tuning yet, then MiniTuner could be for you.

MiniTuner is designed to tune musical instruments (especially guitars) by using a microphone or direct connection through your PC's sound card.

This program automatically detects the pitch of the input signal and displays the corresponding note and its deviation from the targeted note.

Now you've got one less excuse to sound out of tune!
